WebOct 10, 2024 · Schrödinger’s equation requires that the wavefunction have no discontinuities and no kinks (discontinuities in slope) so the x < 0 and x > 0 wavefunctions must match smoothly at the origin. For them to have the same value, we see from above that A = B. For them to have the same slope we must have kA = k1B. http://hepnp.ihep.ac.cn/fileZGWLC/journal/article/zgwlc/newcreate/CPC-2024-0002.pdf; tal-haim samnon memory and variations
